[Current trends in the treatment of mandibular osteoradionecrosis. Use of a sternocleidomastoid osteomyocutaneous flap].

An osteomusculocutaneous flap using the clavicle, and pedunculated on the sternocleidomastoid muscle, was used in two patients to repair loss of post-radicular mucosa and bone substance. Healing of mucosa and bone consolidation was obtained with evidence of production of bone callus on radiography. The hypothesis advanced to explain this reconstruction of necrosed mandible is the presence of the new vascular supply.
